Please keep in mind that the manufacturers have goals to sell four-strokes... by allowing them to race against same sized two-strokes would part the curtains of deception they have draw over the eyes of the motocross public.
Like in the movie The Matrix, we have to help open peoples eyes to the reality of the situation... when enough people switch to two-strokes regardless of the marketing hype and the magazine's rave reviews of four-strokes, the manufacturers will begin to take notice. Maybe.
If they refuse to build two-strokes any longer, we need to begin a new race series like Medios is doing (which I support 100%) or rally the powers that be to allow other manufacturers to race in the AMA Pro Series. There are companies that would jump in to fill the void left by the Big 4....
While we have an interesting road ahead of us, the tide is changing.... it's beginning to lean to the two-stroke side!
Braaappp!
